get fan clutch checked may be blowing air but not enough
my alarm does not work 2004 envoy
If the headlights on the 2004 GMC Envoy are not working, there could be a loose connection somewhere. If all of the other lights are working, it is most likely not a fuse that has blown. Double check the wiring to see if there is a loose connection.
Press and hold the Power I/O button and this should resolve the issue
Its your relay switch... change it out and it should work..
nope
I had the same problem with my 02 Envoy. Check to make sure contacts inside the sockets are intact. I had to replace both of mine. Contact were corroded and rusted out.
the ac does not work when I turn it to 1,2 or 3 it works only on 4
Two comom reasons 1) bulbs are burned out 2) wiring harness has burned out. unfortunatly a common failure on these trucks. See if the wires are melted or crispy. This also pops the fuse. www.trailvoy.com All the answers about the Envoy /Trailblazer platform trucks!
It works because people combined both shampoo and conditioner and they work as both
Turn the ignition over without starting it, push the gas pedal down all of the way three times within 5 seconds, The light will flash indicating you were sucessful, turn ignition to off this locks the reset then start your car and the light should go off. If this does not work, repeat procedure. This worked on 2003, 2004, 2006 envoy, and is suppose to work on all year models. Also check your GMC owners manual under systems management.
If the instrument cluster on a 2002 Envoy is not working, check the fuses. There is a main fuse for this under the hood on top of the battery.
you use freon to cool your car and make the air conditioner work
